Sprayers with double action system

Double acting mechanism

— a feature found in the most compact hand sprayers (see "Design") with a lever principle of operation (see "Type"). The idea of the double action mechanism is that each pull on the “trigger” (pumping lever) provides two sprays — one when pressed, the second when the “trigger” is returned to its original position. This improves productivity and reduces fatigue, especially when spraying for long periods of time.
